ib_dealloc_device(9)

💖 ib_dealloc_device(9) — free an IB device struct 💖

okay bestie so this is a page from the Kernel API Manual, and honestly it's short and sweet — we love a low-effort icon ✨. It's literally just "you allocated a thing, now let it go" and honestly? Growth. 🦋

---

✨ NAME ✨

ib_dealloc_device — free an IB device struct. that's it. that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

void ib_dealloc_device (struct ib_device *device );

no cap, that's the entire signature. void going in, void going out (well, void coming back — she returns nothing, she's mysterious like that 💅).

---

🫶 ARGUMENTS 🫶

• device — the structure to free. this is your struct, the one you're handing back to the kernel so it can go live its best afterlife 🌈. girl is done, let her rest.

---

💅 DESCRIPTION 💅

Free a structure allocated with ib_alloc_device.

that's the whole description, bestie 😭 — it's giving "minimalist queen". So like, the lore here is: if you made it with ib_alloc_device, you un-make it with ib_dealloc_device. It's the matched set, the his-and-his, the duo we don't separate 🔥. literally the pairing is the entire point — don't be out here freeing things you didn't allocate that way, that's not the vibe check you want to fail 🙈.
